Chairman & Senior Executive, IAC/InterActiveCorp, 72
This billionaire business mogul has most likely affected your life without you even knowing it. The chairman of IAC, the company that holds brands like OkCupid, DailyBurn, and About.com, Diller has changed the way we date, work out, and generally go about our daily lives. The bisexual businessman and philanthropist has also mentored men and women who went on to become studio execs at Paramount, Disney, Columbia Pictures, and DreamWorks. He’s married to the sophisticated and sexy Diane von Furstenberg, and this power couple seems to have it all (while keeping their private life pretty private).
